Breathing: The Master Key to Self Healing CD Set by Andrew Weil, M.D. To learn the art of healthy breathing, Dr. Weil turned to Eastern traditions, including yoga, which view the breath as a vital link to the prana, or energy of the universe. In easy-to-follow language, he explains the secret of breathwork's power over your health, and its remarkable ability to influence – and even reprogram – the nervous system. From increasing energy – to lowering blood pressure – to improving circulation – to beating anxiety disorders without drugs – Breathing is a practical introduction to the benefits of breathwork, presented by the bestselling author and physician who has taken the miracle out of self healing, and made it available to all. This set comes with 2 CDs and a study guide
